Correct AnswerA. To convert steam back into water
Quick Explanation
The condenser removes latent heat from turbine exhaust steam and converts it back into water (condensate), while maintaining a low exhaust pressure that improves turbine work output.
Detailed Explanation
Concept & Reasoning
Condensing exhaust steam closes the Rankine water-steam cycle so condensate can be pumped back to the boiler. A good condenser also creates vacuum/low back pressure at the turbine exhaust and facilitates recovery of high-quality feedwater.
How to Solve It in the Exam
Condenser: steam back to water + low turbine back pressure.
Important Exam PointCooling water removes heat from steam; it does not mix with condensate in a surface condenser.
